Struct StreamMatcher

pub struct StreamMatcher<'code> { /* private fields */ }

Available on crate feature stream only.

A struct holding a reference with the &'code lifetime to a dyn FnMut, which is a type-erased vtable.

Implementations

impl<'code> StreamMatcher<'code>

pub fn new( handler: &'code mut (dyn FnMut(StreamMatch) -> MatchResult + 'code), ) -> Self

Create a matcher instance which wraps the provided dyn vtable reference.

Any variables closed over by a closure reference provided to handler will become available again after this object is dropped (which must occur within the span of the 'code lifetime parameter), so any state which is modified by a match callback can be examined once the stream is dropped!
